Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. The Ca2+ gradients are used by the cell to transmit information in a variety of physiol

Difficulties had been identified with regard to bachelor and master theses. The quality varied too much, as did supervision. The report discusses possible ways of improving the situations,looking at other departments at Lund University, as well as the Copenhagen Business School. The report suggests some measures for improving the process as well as for supporting supervisors.

In the early 1970’s, about 80 ha of rich fen, meadows and wet forest on the margins of the largeand pristine raised bog ‘Komosse’ in Southern Sweden were drained by ditches to promote spruce(Picea abies) growth and forestry production. Draining had a dramatic impact on forest productionon the nutrient-rich peaty soils downhill from the ditches. In 40 years, most of the meadows andfens had turned i

The new challenge of the Gas Turbine industry is to develop new technologies for meeting electricity demand growth and reducing harmful emissions. Thus, a better understanding of the combustion phenomenon and an improvement in simulation capabilities are needed. In this paper, we present a new technique that is computationally efficient, for capturing the thermo-acoustic waves in low Mach number c

The enzyme dUTPase catalyzes the hydrolysis of dUTP to dUMP and pyrophosphate, thereby preventing a deleterious incorporation of uracil into DNA. The best known dUTPase is that from Escherichia coli, which, like the human enzyme, consists of three identical subunits. In the present work, the catalytic properties of the E. coli dUTPase were investigated in the pH range 5-11. The enzyme was found to

The increasing test data volume needed to test core-based System-on-Chip contributes to long test application times (TAT) and huge automatic test equipment (ATE) memory requirements. TAT and ATE memory requirement can be reduced by test architecture design, test scheduling, sharing the same tests among several cores, and test data compression. We propose, in contrast to previous work that addresse

This paper presents a phase noise analysis of the very popular differential LC-tank CMOS oscillator. Closed-forms formulas for the phase noise in the 1/f2 region are derived under very general assumptions.
